TERRIFIC DVD DEALS Tracy & Hepburn: The Definitive Collection No one could spar like Spencer Tracy and Katharine Hepburn. Put them on screen together and their fireworks made the Fourth of July seem tame. Nine of the couple’s films are in this nicely priced 10-disc set, including classics like 1949’s Adam’s Rib and 1967’s Guess Who’s Coming to Dinner. (Not Rated, $44.99)

TAXI DRIVER ON BLU-RAY Martin Scorsese and Robert De Niro’s 1976 masterpiece is a 42nd Street fever dream. With its neon lights, steaming subway grates, and wet nighttime streets, it’s also one of the most visually haunting movies ever made. Now it looks better than ever on this deluxe Blu-ray edition. (R, $15.99)

ARTHUR, ARTHUR 2 If a movie about an unrepentantly rich and spoiled drunk sounds like a downer, then clearly you’ve never met Dudley Moore’s Arthur Bach. With a Russell Brand remake hitting theaters April 8, Moore’s hilariously tipsy 1981 comedy and its better-than-it-should-be 1988 sequel, Arthur 2: On the Rocks (both costarring Liza Minnelli!), are now being trotted out in a Blu-ray double feature. (PG, $14.99)

ROGER CORMAN’S ACTION-PACKED COLLECTION The latest in the Roger Corman’s Cult Classics DVD series is a giddy three-pack of Southern-fried car chases, bank heists, and moonshine runs: Georgia Peaches, The Great Texas Dynamite Chase, and Smokey Bites the Dust. Behold the power of cheese. (R, $13.99)

TCM GREATEST CLASSIC LEGENDS: FILM COLLECTION — BETTE DAVIS The Term ”women’s picture” wasn’t coined as a slight. The genre gave us some of the best films of the Golden Age. And no one gave them more punch and sizzle than Davis in these four gems: Dark Victory, Old Acquaintance, Jezebel, and Now, Voyager. (Not Rated, $18.99)
